Oompa Loompas are sad and WebSocket 502

[jpsi...@gmail.com]

Hello, 

First let me say thank you for developing this awesome system. 

I tried to search around to see if I could solve these issues myself but no luck so I am here to ask the community.

My issues: 

I am having websocket issues with the events system and cannot seem to figure out why this is happening.

Console shows:

WebSocket connection to 'ws://projects.domain.com/events' failed: Error during WebSocket handshake: Unexpected response code: 502

Checking the `nginx.error.log` I see this error:

2015/07/31 16:36:37 [error] 13809#0: *249 connect() failed (111: Connection refused) while connecting to upstream, client: 50.253.xxx.xxx, server: _, request: "GET /events HTTP/1.1", upstream: "http://127.0.0.1:8888/events", host: "projects.domain.com"

Also, the Oompa Loompas seem to get sad a lot... When I try to add/manage an issue I see the Oompa Loompas are sad message. The issues are successfully created and all my edits do save. I do have my email configured properly (I validated this by changing my email in the admin user and I did receive the change email properly.)

I see this in the `gunicorn.stderr.log` when this happens:

ERROR:2015-07-31 17:09:41,847: Internal Server Error: /api/v1/issues

ConnectionResetError: [Errno 104] Connection reset by peer

I'm very new to python so I am clueless what to do here...

I installed this on AWS EC2 instance and my current inbound rules are: 

Custom TCP Rule	TCP	8888	0.0.0.0/0
Custom TCP Rule	TCP	8002 - 8003	0.0.0.0/0
All traffic	All	All	0.0.0.0/0
Custom TCP Rule	TCP	9000 - 9002	0.0.0.0/0

HTTP	TCP	80	0.0.0.0/0
HTTPS	TCP	443	0.0.0.0/0

As you can see, I opened all ports. I also disabled the firewall on the server until I can get this working. So I am not thinking this is a port issue but perhaps a missed Listen? 

I setup Taiga by using the Setup Production Environment guide.

I only had an issue when running 

npm install

as gyp was throwing errors  and I had to `sudo` the command to get it to install.

Thanks for your time.

Regards,

Jeremy

Hello Jeremy,

It seems you are having problems with your rabbitmq connection. Did you follow this instructions for configuring the service? -> http://taigaio.github.io/taiga-doc/dist/setup-production.html#_events_installation

Hello Alejandro,

Thanks for your assistance.

Yes, I followed that exactly. I did figure out that special characters seem to be to culprit in my case. By changing the password I was able to get that working. (I was using a $ and !, by removing them it works)

Now I get this when loading the Issues page:

{
    "_error_message": "No StorageEntry matches the given query."
}

This is my console when I load the Issues page:

Don't worry about the storage error, it sounds like you are using the autocreated admin user instead of a registered one, is it possible?. issues should be working anyway and the error shouldn't appear with a registered user.

About the events error, it seems the problem is nginx can't proxypass to "http://127.0.0.1:8888/events", I think there are two options or events app isn't running correctly (you could check if that port is open on localhost and try to access) or the nginx configuration isn't ok.

Thanks again Alejandro.

Yes, I just renamed the default admin to my user. 

I went ahead and created a new user and gave them admin access. 

I noticed I still get the same error:

GET /api/v1/user-storage/f250e66cf068b06e308298a1bac5052c9e18eca9

HTTP 404 NOT FOUND
Content-Type: application/json

Allow: GET, PUT, PATCH, DELETE, HEAD, OPTIONS

Vary: Accept

{
    "_error_message": "No StorageEntry matches the given query."
}

As for the proxypass, this is my first time dealing with nginx so I may be missing something. 

I had my firewall disabled but I did turn it back on. I have this for my firewall:

$ sudo ufw status

Any suggestions?

[Alejandro Alonso]

So it seems taiga events isn't running correctly. Can you manually launch it executing "coffee index.coffee" ?

You should finish with something like (executed from another shell):

netstat -na | grep 8888
tcp        0      0 0.0.0.0:8888            0.0.0.0:*               LISTEN

Thanks again Alejandro.

That seems to make it work.

$ netstat -na | grep 8888

tcp        0      0 0.0.0.0:8888            0.0.0.0:*               LISTEN 

Now I no longer have the websocket errors but when I exit out, obviously it kills the script so the errors come back.

It seems this is the last issue I have asides from the user-storage issue that I get for all users.

So it seems it has an issue auto-starting. Any suggestions? 

Thanks,

Jeremy

[David Barragán]

The user-storage error is a "valid" one: when you access to the issues list view taiga-front ask to taiga-back if the user has some custom filter (saved in user-storage). This error means the user hasn't custom filters saved.

Thank you for the explanation David. That makes a lot of sense. 

So it looks like my only issue is to get the events to autostart.

Running:

coffee index.coffee

Works perfectly but I just need it to auto-start.

Thanks,

Jeremy

[Alejandro Alonso]

Hello Jeremy, 

If you can run it with "coffee index.coffee" command the problem should be in the circus part, Could you please show us your circusd config file?

My /etc/init/circus.conf is:

start on filesystem and net-device-up IFACE=lo

stop on runlevel [016]

respawn

exec /usr/local/bin/circusd /home/taiga/circus.ini

[Alejandro Alonso]

The configuration related to taiga-events is:

[watcher:taiga-events]
working_dir = /home/taiga/taiga-events
cmd = /usr/lib/node_modules/coffee-script/bin/coffee
args = index.coffee
uid = taiga
numprocesses = 1
autostart = true
send_hup = true
stdout_stream.class = FileStream
stdout_stream.filename = /home/taiga/logs/taigaevents.stdout.log
stdout_stream.max_bytes = 10485760
stdout_stream.backup_count = 12
stderr_stream.class = FileStream
stderr_stream.filename = /home/taiga/logs/taigaevents.stderr.log
stderr_stream.max_bytes = 10485760
stderr_stream.backup_count = 12

 

[env:taiga-events]
PATH = /home/taiga/.virtualenvs/taiga/bin:$PATH
TERM=rxvt-256color
SHELL=/bin/bash
USER=taiga
LANG=en_US.UTF-8
HOME=/home/taiga
PYTHONPATH=/home/taiga/.virtualenvs/taiga/lib/python3.4/site-packages

But it seems to be ok, could you simulate the circusctl behaviour?:

cd /home/taiga/taiga-events
/usr/lib/node_modules/coffee-script/bin/coffee index.coffee

Did you check the files  /home/taiga/logs/taigaevents.stderr.log and /home/taiga/logs/taigaevents.stdout.log? and the circus log? 

Did you try reloading the circus config and restarting taiga-events?:

circusctl reloadconfig
circusctl restart taiga-events

Why did you add the entry [env:taiga-events]?, we don't use it in our instances, may be it's related to your problem. You could also try removing it from the file, reloading circus and restarting taiga-events.

Regards!,

Thanks again Alejandro!

I added the env because I noticed it for all the others and I was just seeing what it would do as I had this issue from the start.

My error taiga events error log is empty.

nginx does show:

2015/08/07 14:03:50 [error] 1198#0: *70 connect() failed (111: Connection refused) while connecting to upstream, client: 50.253.135.181, server: _, request: "GET /events HTTP/1.1", upstream: "http://127.0.0.1:8888/events", host: "projects.olympusat.com"

When I ran 

cd /home/taiga/taiga-events
/usr/lib/node_modules/coffee-script/bin/coffee index.coffee

I saw:

-bash: /usr/lib/node_modules/coffee-script/bin/coffee: No such file or directory

did a

whereis coffee

I noticed my pathing is different.

I updated my pathing for the cmd and it works now!

My config for events is:

[watcher:taiga-events]

working_dir = /home/taiga/taiga-events

cmd = /usr/local/bin/coffee

args = index.coffee

uid = taiga

numprocesses = 1

autostart = true

send_hup = true

stdout_stream.class = FileStream

stdout_stream.filename = /home/taiga/logs/taigaevents.stdout.log

stdout_stream.max_bytes = 10485760

stdout_stream.backup_count = 12

stderr_stream.class = FileStream

stderr_stream.filename = /home/taiga/logs/taigaevents.stderr.log

stderr_stream.max_bytes = 10485760

stderr_stream.backup_count = 12

Thanks for all your assistance for my issues.  Very much appriciated :)

Thank You

Jeremy 

[Alejandro Alonso]

Hello!,

It sounds like your settings in local.py for connecting to rabbit aren't correct, could you show us your local.py file?
